I have a question that I hope someone can answer for me. I've owned about a dozen or so digital currencies as far back as 2012. Ethereum is one I am still trying to understand. My question is this - How does the functionality of Ethereum (it's blockchain and all that comes with it), convert to the valuation of one ETH being worth $300, or $500, or $100, etc.? How will ETH (the digital currency) be used that will give it these valuations? I understand other currencies. Take Ripples XRP for example; the more banks that are transacting with XRP, the higher the demand is for XRP, which equates to a higher valuation of XRP. So how does Ethereum and ETH get their values? Can companies use Ethereums service without increasing the demand for ETH (digital currency)?
